PENBRITIN vs PROBAMPACIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin G inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity and preventing peptidoglycan cross-linking, leading to cell lysis.
PROBAMPACIN is a synthetic aminoglycoside antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, causing misreading of mRNA and preventing translocation of peptidyl-tRNA from the A-site to the P-site.
250-500 mg orally every 6 hours; 500 mg to 2 g intramuscularly or intravenously every 4-6 hours.
100 mg IV every 12 hours over 30 minutes.

0.5-1 hour in normal renal function; extended to 2-6 hours in renal impairment. Hemodialysis shortens half-life.
4.5 hours (prolonged to 12-18 hours in severe renal impairment)
Renal: ~75-90% unchanged via glomerular filtration and tubular secretion. Biliary: ~10% in feces. Minor hepatic metabolism to penicilloic acid.
Renal: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
